Subject: [PATCH 1/3] test/daxctl-devices.sh: increase the namespace size
|
||
|
|
|
||
|
|
Memory hotplug requires the namespace to be aligned to a boundary that
|
||
|
|
depends on several factors. Upstream kernel commit fe124c95df9e
|
||
|
|
("x86/mm: use max memory block size on bare metal") increased the
|
||
|
|
typical size/alignment to 2GiB from 256MiB. As a result, this test no
|
||
|
|
longer passes on our bare metal test systems.
|
||
|
|
|
||
|
|
This patch fixes the test failure by bumping the namespace size to
|
||
|
|
4GiB, which leaves room for aligning the start and end to 2GiB.
